I can't answer directly, because it depends on your skills.
If you have low skills, you will gain more points using the same training than if you use this training but having high skills.

I mean if you have braking = 50 points and do 1 day training, it'll give you 8-9 points.
But if you have 900 points already, it will give half of this.

In a week we will release new feature in training - before you start you will see how much avg skills you will have at the end of the training.

We can add an idea to our todo list that you will see how all of your trained skills will change at the end of a training, but there is a possibility to see it right now.

You start training, then click on speed-up. You'll see how much you get at the end of a trianing. You can then click "cancel", then "abort training" and then you can start new one with different settings and see a difference.
